Welcome to the home of MCPL, a binary file format for usage in physics simulations.
MCPL files contain lists of particle state information, and allows for easy storage and interchange of particles between various Monte Carlo simulation applications. It is implemented in portable C code and is made available to the scientific community, along with converters and plugins for several popular simulation packages.
MCPL is described in great detail in the MCPL paper, and in particular details of the file format itself can be found in section 2. The present web-page serves as an online home for MCPL, providing both quick recipes and updated information where needed. You can download and try out the MCPL distribution right away, or use the menu above to navigate to more information.
